Electrostatic force?

1. The problem statement, all variables and given/known data
Two very small spheres are initially neutral and separated by a distance of 0.50 m. Suppose that 6.2 x 1013 electrons are removed from one sphere and placed on the other. What is the magnitude of the electrostatic force that acts on each sphere?,

2. Relevant equations
Each electron carries an amount of charge with magnitude e=1.6*10^-191. The problem statement, all variables and given/known data

Q2. Two particles, with identical positive charges and a separation of 3.80 x 10-2 m, are released from rest. Immediately after the release, particle 1 has an acceleration a1 whose magnitude is 6.71 x 103 m/s2, while particle 2 has an acceleration a2 whose magnitude is 9.64 x 103 m/s2. Particle 1 has a mass of 7.46 x 10-6 kg. Find (a) the charge on each particle and (b) the mass of particle 2.
